Abstract (en)

[origin: US11271247B1] Methods of forming an electrochemical cell using a non-inert gas are disclosed. Exemplary methods include providing a first gas before applying or more of current and voltage to the cell. The first (e.g., non-inert) gas can facilitate formation of a solid electrolyte interphase (SET). Further examples of the disclosure relate to methods of forming an electrochemical cell or portion thereof by electrospraying a solution including polymeric material. Such methods potentially eliminate a step of compressing the cell at a pressure beyond 100 MPa and prolong the cycle life while preventing a fire hazard.
